If you fu*k around and stay in an armbar for too long, and you're not 100% sure that you can get out. You're sh*t gets broken. That's a couple months out of training=money out of your pocket if f!ghting is your main income.

Tapping to a joint lock is the smart thing to do. Take the L and train another day. That's what my coach taught me....If it's a choke though...fu*k it, go to sleep.
